A couple of 1jz running issues, high rpm break up, miss at idle, and much more

Thanks for the responses! I went for a drive today, and i think i've fixed the problem, well for now at least, spark plugs are at .024, and i used some grease around the spark plugs (it was sitting at the checkout at autozone in what looked like a condom package). So for now i don't have the break up, i just have epoxy and a little piece of heat shrink on the coil packs, along with the grease and .024 gaps, i do not have a wideband yet, but i'm going to get the Innovate MTX-L would that be a good choice? only $200! should be just as good as the lc 1 right? anyway i for some reason am having extreme difficulty connecting the speedo cable to the trans, so it isn't hooked up at the moment lol, could this have caused any problems? It threw a code 42 towards the end of the drive.

Other updates, i no longer get the loud popping on cold starts, although it seems to eject oil out of the exhaust, or idk maybe its just condensation cleaning out the exhaust pipe that has been sitting for 6 months. Heres a quick current vid

Speedo shouldnt be a problem unless your auto.

Its easier to install with a jack under the trans and take off the metal mount or just drop it down.

Haha, I totally missed that post Jay, sorry about that. My car never seemed to be running lean when it would fuel cut on me, was still reading solid low 12:1 AFR's... Thought it was just boost pressure that the MAP sensor felt was a good time to step in and stop the fun?

I don't know if this has been brought up yet, but I just had a similar issue, Braking up @ around 4-5k on boost.
Had to lover my base FP about 8 psi + retune, solved the problem.
